INVERTED INCANDESCENT GAS-LIGHT.

To all whom it may concern:

Be it known that I, ARTHUR E. SHAW, a citizen of the United States, anda resident of Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inInverted Incandescent Gas- Lights, of which the following is aspecification.

The principal object of the present invention is to provide simple,eflicient and comparatively inexpensive means for supporting from theburner tube the burner and chimney in such a way that the various partsmay be readily assembled and in such a way that the glass part of thechimney can be easily detached and applied.

Other objects of the invention will be more fully understood from thefollowing description which will be made in connection with theaccompanying drawings, in Which Figure 1, is a side view partly insection of the upper portion of an inverted incandescent gas burner,embodying features of the invention. Fig. 2, is a perspective View ofone of the parts removed, and Fig. 3, is a sectional View taken on theline 33 of Fig. 1, looking upward.

In the drawings 1 is the depending portion of a burner tube and it isshouldered and threaded at its lower end.

2, is the upper portion of the chimney and it may be of White enameledmetal. The chimney top 2 may be provided with a spider 3, having at itscenter an opening through which the threaded end of the burner tubepasses. The top 2, is secured to the ends of the arms of the spider 8,as by rivets. 1, is nut applied to this threaded end of the burner tubeso as to hold the spider to place thereon. The chimney top 2 is providedwith an opening 5, through which the burner tube passes.

6, is a chimney holder and it consists of a spider 7, the shanks of thearms of which lie in the plane of the ring at its center and thesucceeding portions of these arms are bent downward and outward as at 9,where they are riveted or otherwise secured to a ring or band 10. Thelower ends of these arms extend generally downward from the ring 10 andare then curved outwardly as at 11. The ends of the arms have punchedfrom them spring tongues 12, the free ends of Specification of LettersPatent.

Application filed March 31, 1909.

Patented May 10, 1910.

Serial No. 488,903.

The short section of pipe or thimble 14:, is

screwed onto the end of the burner pipe and serves to firmly secure thechimney holder to place. On the end of the thimble 14:, the mantleholder 15 may be screwed.

The glass chimney 16 is flanged below its top as at 17. Evidently theglass chimney can be inserted to place in the chimney top by simplypushing it therein with the result that the tongues 12 spring past andunder the flange 17. Similarly this chimney 16 can be withdrawn from thechimney top.

The mantle holder 15 can be readily applied to and detached from thethimble 1st and the latter can be detached from the threaded end of theburner tube 1, so as to permit of the removal and application of thechimney holder 6. Even when the parts described have been removed, thechimney top remains in place, but it can be readily applied and removedby putting on or taking off the nut l.

The described arrangement is not only useful for the reasons described,but is also attractive in appearance and adapted to protect the mantlesand promote a good draft for the flame by which they are heated.

It will be observed that the glass chimney 16, is open at the bottom andcontracted toward the flange at the top where the open ing is smallerthan it is at the bottom and it will also be noted that the chimney top2 is of smaller diameter than the top of the glass chimney 16, so thatthere is a gradual reduction in size from the bottom to the top of thecombined chimney. Between the ends of the arms 11 and the chimney 16,there is space. The chimney depends from the ends of the tongues 12. Thepresence of this space opposes breakage and the ends of the arms 11, ineffect, constitute guides by which the chimney is directed when appliedor removed.

What I claim is:

1. A chimney holder for inverted incandescent gas lights which comprisesa spider having at its top a ring provided with arms having their shanksin the general plane of said ring and having their intermediate portionscurved downwardly and outwardly, a band surrounding and connected tosaid intermediate portions and having their ends curved outwardly andprovided with spring tongues which project inwardly and upwardly,substantially as described.

2. A chimney holder for inverted incandescent gas lights which comprisesa spider having outwardly and downwardly extending arms provided neartheir ends with inwardly and upwardly extending spring tongues, and aband encircling and connected with said arms, substantially asdescribed. I

3. In combination a burner tube having a threaded depending end, achimney holder having a spider fitted onto said end, means applied tothe threaded end for retaining the chimney holder, and amantle holderdetachably applied to said means whereby the mantle holder can beremoved without disturbing the other parts, substantially as described.

4. In combination a burner tube having a threaded depending end, achimney top having a spider applied to the burner end, a nut applied tothe burner end for clamping said spider, a chimney holder having aspider applied to the burner end and arranged within the chimney top, athimble applied to the burner end for holding the chimney holder, and amantle holder detachably applied to the thimble, substantially asdescribed.

5. A chimney holder for inverted incandescent gas lights comprising aband, a spider connected with said band, and arms depending downward andoutward from the band and provided near their ends with upwardly andinwardly projecting spring tongues, substantially as described.

6. A chimney holder for inverted incandescent gas lights comprising aband, a spider connected with said band, and arms depending downward andoutward from the band and provided near their ends with upwardly andinwardly projecting spring tongues, in combination with a chimney havingnear the top thereof a flange engaged by the ends of said tongues fromwhich the chimney depends, substantially as described.

7. The combination, in an inverted incandescentgas light of a chlmneyholder having spring tongues extending upwardly and inwardly, and achimney having near its top a flange engaged by the ends of the tonguesand from which it depends.

In testimony whereof I have hereunto signed my name.
